<P>PROBLEM TO BE SOLVED: To clearly display an image radiographed by rotating a radiographing part on a display part, to prevent erroneous recognition of irradiation field extraction processing caused by the rotation, and to obtain an image to be excellently read. <P>SOLUTION: An X-ray radiographing system irradiates a patient with X rays emitted from an X-ray source and takes transmitted X rays by a radiographing part to digitally obtain X-ray image data. Then, the X-ray radiographing system is provided with a rotation means for rotating a radiographing part on a vertical plane with respect to an X-ray incident axis; an input means for inputting rotation angle information of the radiographing part generated by the rotation means; a storage means for storing the image data and the rotation angle information; and a display image preparation means which rotates the image data according to the rotation angle information in the case of displaying the image data read from the storage means and which adds a dark part between a rectangle which circumscribes the respective ends of the bottom part, the top part, the rightmost part, and the leftmost part of the image data after rotation and which has horizontal bottom edge, and the image data. <P>COPYRIGHT: (C)2004,JPO |
